f IMPROVEMENT IN NAIL-FEEDING MACHINES.

' l Specification forming 'part of Letters Patent No. 181,376, datedAugust 22, 1876; `application led Mayaa, 181e.

To 'all whom it may concern Be it known that I, FRANK ToEPFER, ofMilwaukee, in the county of Milwaukee and State of Wisconsin, haveinvented an Improvement in Nail-Feeding Machines, of which the followingis a specification The invention consists of a descending trough, inwhich the nails hang by the heads, points downward, arranged so as todrop the nails horizontally into a hopper in advance of the slidingdriver, on which trough are a couple of blades, arranged side by side,with space for one nail between them, which are so geared to the driverthat when it goes forward to drive the nail in advance of ,it the upperblade draws back, and the lower one goes forward to receive the lowestnail in the trough against it', and when the driver goes back the arenails to be driven into one side ofthe box to be nailed, and the driverswill be adjustably connected for shifting toward and from each other,according as the lnails are to be driven more or less distant from eachother.

Figure l is a longitudinal sectional elevation `of the machine, in linex w, Fig. 2. Fig. 2 is a plan view, and Figs. 3 and 4 are details.

Similar letters of reference indicate corresponding parts.

A represents the trough, in which the nails hang side by side by theheads, and'slide down into the hopper B in advance of the driver G,being delivered one by one by the blades D and E, the blade D beingpushed forward by the driver-stock F, which goes back between the naillying, against blade E and those above it, and the blade E being drivenback at the lmoment the driver arrives at the limit of the back stroke,to let the nail fall down into the hopper B, in front of the driver.

At the forward movement of the driver, the blade E is again pushedforward to arrest the nails', which are thenl let down against it by thewithdrawal of the blade D.

The blade E is connected to the driver-stock by the slotted link G andstudpin H, lso that it rests while the driver stock is moving throughthe greater part of its travel, but afterward moves in the samedirection, while the blade D is connected by the lever J and said linkG, so that it movesin the reverse direction.

The trough terminates at the lower end in a slanting tube, K, ontothelower side of which the nails drop, so as to slide out at the lowerend, and drop sidewise into the hopper, with the head next to thedriver, said tube being suitably located above the hopper for thatpurpose.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- A l. The combination of the reversely-slidin gcut-off plates E D with the feed-trough A, hoppose set forth.
